Hi Sweepy
We went to Grenada 5 yrs ago in July and stayed at the Rex Grenada. The weather was good, had the odd shower through the day, but just used to dive under the bar canopy and wait a few seconds for it to pass.
We hired a taxi driver for the day and he took us on a tour of virtually the whole island. Also visited the cocoa plantation and of course where they make the rum. The people are lovely, very friendly and helpful and a visit to St Georges market is a must. I think it could be quite expensive though if you dont go AI. Sorry I cant be more helpful, my memory is getting worse as I get older !!
